the 1990 II Morrow Inc. Tigershark LORAN-C unit.

In the days before GPS most anglers relied on their depth finders and visible point on land to line up on offshore structure. Yes there was the LORAN-C technology used by the saltwater sportfishing industry but those units were too costly and didn’t offer pin-point accuracy for the bass angler. They were good enough to put you in an area but if you wanted to set up on a pinnacle or a specific spot on a drop, you had to use your depth finders, line-up points and a lot of experience.

Then in 1990 a company out of Oregon named II Morrow Inc. came out with a version of the LORAN-C called the Tigershark LCL. They were targeting the recreational boating market – namely bass anglers – with a low-cost substitution for more expensive LORAN-C units. The unit was sized to fit on a typical bass boat and had all the features that a bass angler would use like a 12-key touch pad, automatic station selection, low power requirements, 100 waypoint memory and navigation displays.

Loran C 2Even though the unit had everything a bass angler would want, unfortunately LORAN-C signals weren’t that accurate, especially at dawn, dusk and during solar flares. Even when everything was perfect, LORAN-C was only acurate within a tenth to a quarter mile – not accurate enough to find that rock or brushpile you sunk two weeks ago.

I don’t recall any bass angler ever putting the II Morrow Inc Tigershark on their boat and I never heard what the retail price was. Most anglers through the mid ’90s still relied on the use of maps and points on land to find their honey holes. Needless to say the Tigershark LCL didn’t last too long in the industry and by 1997 GPS was taking over the world.

Did any of you readers out there have one of these?

    Didn’t ever try one on fresh water, for the reasons you cite. It wasn’t accurate enough. However, as an old AF navigator I found them useful in salt water to put a larger boat on a kelp patch (think Horseshoe) or rockpile. The boat still had to circle around to locate a particular feature with sonar. Loran-C units were also useful in the open ocean to help the pilot keep a boat in an area fish were seen surfacing or feeding on top.
